Wang has extended TIFF tags but what is the problem here?
What are the "traditional methods of open tiff image" that don't work?
A properly implemented TIFF loader either understands the tags it needs and can open the image
or if it can't follow the tags then the format is unsupported or the TIFF image is malformed.
If GDI+ can open it then it's probably a valid TIFF image. If the format is not supported by
Photoshop then that's Adobe's problem.
What is your question?

my question is i do not want open with GDI+,and i want use the code which i programed. so i want know the tag format,then i can open it by my application.

Then you'll need to know the TIFF specification.
It's held by Adobe and can be found online here[^]
If you run in to problems just ask

The version of the platform SDK is not necessarily compatible with VC6. The latest that MS recommend you use is FEB 2003, although I've also found that the XPSP2 update one works.

Thank you Steve, let me check with that and get back to you..

Hi,
I Select an Image on to a CompatibleDC .I get each Pixel and check to see whether Red,Green,Blue of that Pixel are same or not.If so I perform Some Operations and change the color of that Pixel Using SetPixel.
and then Finally I Stretchblt it on to my ClientDC.
HBITMAP hBmpObjSmpl = imgObjSample.GetBMP();
bmpSample.Attach(hBmpObjSmpl);
CDC dcMem;
dcMem.CreateCompatibleDC(pDC);
HBITMAP hOldBitmap=(HBITMAP)dcMem.SelectObject(bmpSample);
BITMAP bm;
bmpSample.GetBitmap(&bm);
for(int i=0;i < bm.bmWidth ; i++)
for(int j=0;j < bm.bmHeight ; j++)
{
COLORREF clr = dcMem.GetPixel(i,j);
int R = GetRValue(clr);
int G = GetGValue(clr);
int B = GetBValue(clr);
if( (R == G) && (G == B))
{
R = (R-nMaxRGB) + dblSampleRGB[0];
G = (G -nMaxRGB) + dblSampleRGB[1];
B = ( B -nMaxRGB ) + dblSampleRGB[2];
R=R*dblillumination;
G=G*dblillumination;
B=B*dblillumination;
if(R>255)
R=255;
if(R<0)
R=0;
if(G>255)
G=255;
if(G<0)
G=0;
if(B>255)
B=255;
if(B<0)
B=0;
dcMem.SetPixel(i,j,RGB(R,G,B));
}
}
pDC->SetStretchBltMode(HALFTONE);
pDC->StretchBlt(rcSample.left,rcSample.top,rcSample.right-rcSample.left,rcSample.bottom - rcSample.top,&dcMem,0,0,bm.bmWidth,bm.bmHeight,SRCCOPY);
dcMem.SelectObject((HBITMAP)hOldBitmap);
bmpSample.DeleteObject();
dcMem.DeleteDC();
As I need to Perform the same Operation 16 times in my OnPaint() to view the picture 16 times in 4x4 row matrix its becoming very slow.I could see each row painting and its taking around 3 secs .
Each time the Operation is Performed only these values dblSampleRGB[0],dblSampleRGB[1],dblSampleRGB[2] in code logic vary.
I want the whole OnPaint Operation to be Performed Instantaneously. So any suggetions to Optimize my code would be helpful.
Thanks

I haven't gone through your code but I would like to suggest a memory bitmap.
Write a dedicated class called CMemDc and ask it to do the stuff for you. Search google with "Memory DC VC++".
Directly doing the drawing into this dc and dumping the drawing will help in reducing flicker. Saving this drawing will help further. But you will have to take care of other things.
These are some quick suggestions.

Using GetPixel and SetPixel is SLOW! Every call needs to calculate the offset into the pixel
data.
I would start with a DIBSection - an HBITMAP that can be selected into a DC but you can directly
access the pixel data using a pointer.
See CreateDIBSection[^]
The CImage class can help wrap the DIBsection since you're using MFC.

Hi All,
In my application i need to identify the drives available in my PC and the type(Ex: USB Floppy / Removable Disk etc -- The same way as shown in "MyComputer")
But while using the "GetDriveType" API, it returns only the type as DRIVE_UNKNOWN / DRIVE_REMOVABLE etc., But here i should know whether its a USB floppy or a removable one. Can anyone of you help me?
Thanks in advance.
Thanks & Rgds,
Sri..

Hi,
Hope this helps ...
Take the following into consideration, and then have a look a the function _getdrive() on MSDN.
curdrive = _getdrive();
for( drive = 1; drive <= 26; drive++ )
{
if( curdrive == drive )
{
sprintf(lpdrive, "%c:\\", drive + 'A' - 1 );
sprintf(szDirPath,"%s",lpdrive);
CreateDirectory(szDirPath, NULL);
}
}
Regards,

Sorry didn't read the whole question ... thus my answer won't help, seeing that you want the physical name. 
The only programmers that are better than C programmers are those who code in 1's and 0's.....

"QueryDosDevice" API shall be used for getting the deivce path name. And after that we can search for the string "floppy" in the return string of QueryDosDevice.
Thanks & Rgds,

Hi
what is the difference bet these throw.
void Fun() throw();
void Fun() throw()=0;
void Fun() throw(bad_alloc)=0;

Yes.
See Steve's reply for this.
vibindia wrote: void Fun() throw()=0;void Fun() throw(bad_alloc)=0;
I guess, there should be virtual specifier mentioned.
These are pure virtual functions(assuming virtual specifier).

Yes
This actually means that the function does ***NOT*** throw any exceptions. On a compiler that supports exception specifications if the function does try to throw one std::unexpected is called which usually terminates the program.

Thanks for correction !

ya now i got it. They are having virtual keyword.(pure virtual function>
i was confused with that throw() in betweeen
virtual void Fun() throw();
virtual void Fun() throw()=0;
virtual void Fun() throw(bad_alloc)=0;
